I hope you can help with some simple PWM questions.
I've got an old treadmill I'm trying to reclaim. It has a PWM motor (burned out controller) that is marked as such:
120VDC
18A
2.5 HP
3800 RPM
1865W
As a first pass, I want to just buy a (cheap) PWM controller and play with it, but I can't find many that get up to 120VDC: for example, here are stats on one:
Specification:
If I drive my motor with lower voltage (than it's rating), do I risk burning it out, or have inadequate power from the motor? (those are my two fears).
Does the controller listed here seem capable of powering this motor?
Can you help clarify any of this for me? Sorry they are such basic questions.

As a first pass, I want to just buy a (cheap) PWM controller and play with it, but I can't find many that get up to 120VDC: for example, here are stats on one:
Specification:
- working voltage: DC10v- DC 50V
- Rated current: 40A(Maximum output current)
- Control Motor Power : 0.01-2000W,
- working voltage 50V: 50V*40A=2000W(max)
- quiescent current:0.025A
- PWM Regulation range:5-100%
- PWN Frequency : 12khz
